Summary: The authors enthused by the seemingly simple `napkin problem'. This might be described as a result of unintended consequences. Allowing oneself to be sidetracked is something time often will not `allow', but on occasions curiosity overcomes the `time' demon. Here is a welldocumented account of following a mathematics byway because it was interesting. Post Conference 2013 the intrigue continued through an inset session, and beyond. You might need to have some square paper napkins to hand as you read the account, which might provide a new take on the term `absorbent'when applied to the humble napkin.
